Abstract
A storage system has a resiliency scheme to enhance storage system performance. The storage system composes a RAID stripe. The storage system mixes an ordering of portions of the RAID stripe, based on reliability differences across portions of the solid-state memory. The storage system writes the mixed ordering RAID stripe across the solid-state memory.
Claims20
A method for a resiliency scheme to enhance storage system performance, performed by a storage system, comprising:
- composing a RAID stripe of data to be written across solid-state memory of the storage system;
- mixing an ordering of portions of the RAID stripe of data, based on reliability differences across portions of the solid-state memory;
- and
- writing the mixed ordering RAID stripe of data across the solid-state memory.
A tangible, non-transient, computer readable media having instructions thereon for one or more processors to perform a method, comprising:
- composing a RAID stripe of data to be written across solid-state memory of a storage system;
- mixing an ordering of portions of the RAID stripe of data, based on reliability differences across portions of the solid-state memory;
- and
- writing the mixed ordering RAID stripe of data across the solid-state memory.
A storage system, comprising:
- solid-state memory;
- and
- a processing device to:
- compose a RAID stripe of data to be written across solid-state memory of the storage system;
- mix an ordering of portions of the RAID stripe of data, based on reliability differences across portions of the solid-state memory;
- and
- write the mixed ordering RAID stripe of data across the solid-state memory.
